Yep. I took me a while to decide, but Wendy is my favorite character. The reason so, is because her character development. She started out as a shy little girl who didn't like fighting and grew into a powerful mage who helps her friends in time of need. Not mention, she is so frickin' adorable!
She's originally who I was going to put as my favorite, but I've come to like Wendy a bit more. Erza was my favorite character since the beginning, she's just a badass and my wife. <3
I don't really need to explain this one do I?
